To all whom it may concern: r

Be it'known that I, GEORGE Doarrnn, a citizen of the United States, and a resident of Oaklanchin the county'of Alameda and State of California, have invented a new and Improved Pump of which the following is a full, clear, and exact description.

This invention relates to pumps and ticularly to an improved arrangement of pump which elevates water or other liquid through the use of compressed air.

An object in view is to provide a new construction and arrangement of parts in a pump which will utilize compressed air as a motive power in such a way that the pump will be automatically operated continuously as long as the water is permitted to flow or the air turned on. i

A still further object of the invention is to provide an improved arrangement of water pu'aip forutihzing compressed air as the propelling medium, the parts being so arranged that the expenditure of air Wlll, be

reduced to a minimum.

tion a pair oi tubular members are provided formed with aoertures in the lower part thereof forthe admission of water. These members or tubes are adapted to be entircly or almost entirely submergedso that a floatin each of the tubes will be raised by the water enter ng therein under certain circiunstances. The various floats used in this I device act as valves when lowered and coact with outlet valves so that during the operathe various'tubes will operate successively.

In the accompanying drawings :Figure l is a side view ofthe air controlling valve and associated pa1'ts,'tlie operating tanks and associated parts being shown'in section for better illustrating the construction; Fig. 2 is a side view on a somewhat enlarged scale of the tubular members or pipes arranged in'the well.

1 n carrying outthe objects of the inven- {5 is an edge view 'ofthe valve'member shown in Fig. 4, the same being taken on line 5-5 of said figure. Fig. 6 1s another edge view of the valve shown in Fig. 4%, the same being identical construction a description of'one will be sufficient for both; Pipe 4 may be made into sections and connected together by su table tubular members threaded together as shown in Fig.2, the upper part of the pipe being provided with a cap 5 to which an air tube 6 is ccnnected sothat air may be introduced into the top. of the pipe whenever necessary, as hereinafter fully described. {Thebotto-m of the pipe is prefer-v ably provided witha cap 7 but a bottom section or portion of the pipe is formed with a plurality of apertures 8 through which the water may freely pass and from thence up wardly through the spider 9 and the valve seat 10, a valve member 11 being normally Patented Dec. 2e, 1916.1 Application filed March so, 1916; Serial No. 87,716

unseated by the' spring 12, Spring 12 is preferably a comparatively weak spring and is intended to raise the valve 10 slightly oif its seat when the pressure on opposite sides of the valve is equalized.

Immediately above the valve 11 is an outlet elbow 18 to which a pipe 14' is connected by being threadedthereto or secured in any suitable way. The pipe 14: has a casingel5 connected therewith which casing has a valve 16' arranged therein adapted to coact with the seat 17 Valve 16 is normally held closed by a spring 18 acting againstthe enlargementl.) and against the spider 20. To the upper end of thecasing 15 is connected a pipe 21, which pipe in turn is connected to a fitting 22 discharging into an outlet pipe 23, which outlet pipemaydi'rect the water to a storage tank onto anyother place preferred.

Pipe 3'is provided with a valve 24 and other parts similar to valve 16 and'associated parts so that water may be discharged at one time past valve 16 and at another time past valve 24:, whereby a substantially continuous stream is'supplied to the outlet pipe 23.

Arranged inthe ipes a short distance above the elbow13 is axring QSintowhiCha tubular member 26 is fitted, said tubular member having connected therewith a plus ralityor" uprights 27 forming guides for the water and again automatically caused ta float 28 which is preferably formed of Wood. A connecting member or cap 29 is secured to the upper ends of members 27 for limiting the upward movement of the float. The tubular member 26 is provided at its upper end with a smooth portion 30 acting as a valve seat against which the washer 31 secured to the float 28 presses when the Heat is in its lowered position, as shown in dotted lines in Fig. 2.

In operation, when air under pressure is allowed to pass through pipe 6 into the upper part or" pipe 4, as shown by the arrow, the water in the upper part of pipe 4 will be forced downwardly, the first movement causing valve member 11 to seat and a con tinued movement causing part of the water to pass upwardly through elbow l3 and finally out past the valve member 16. The water will continue to flow until the float 28 has become seated on member 26. At this time the air will be shut off from pipe 6 by mechanism hereinafter fully described and turned on to pipe 32 so that the moving parts in pipe 3 may operate in a similar manner to the parts just described for fore ing water past valve 34-. As soon as the air has been shut oil from pipe 6 and said pipe has been exhausted to the atmosphere or some other place so aStO relieve'the pressure in pipe 4, the pressure or tensionof the water above and below the valve member ll'will become equal and, consequently, valve member 11 will become unseated so that the head of water in the well will cause some of the water to flow through apertures 8 and reestablish the head of water in the pipe 4. This, of course, will raise the float 28 to its highest position. After the parts in the pipe 3 have operated for causing a discharge of the water the air will be turned 'ofi from said pipe and again switched on to pipe 4 so that the cycle will be repeated. In fact, this cycle is repeated continuously as long as the air is being turned on and ofi by the mechanism hereinafter fully described.

Referring more particularly to Fig. 1, a mechanism will be seen which is intended to turn on and oil the air so as to operate the parts shown in Fig. 2, this mechanism being designed to be mounted at the top of the well or at any other convenient point. Air under pressure is designed to be supplied to the feed pip 33, said air being pro-' vided by an air pump or by a tank filled with compressed air, the same forming no part of the present invention. If desired, a valve may be arranged in pipe 33'for turning the air on and off whenever desired, but if said valve is not turned off the pump may be stopped by shutting off the operate by merely turning the water on again. Th .,p1pe 33 is connected with casing 34, as'more clearly shown in Fig. 3, so that the compressed air may pass through the inlet port 35 into the cut away portion 36 of the valve member 37. Valve member 37 is not only provided with the cut away portion 36 but with a passageway 42 and with exhaust ports 38 and 39. Exhaust ports 38 and 39 are designed to exhaust into the exhaust passageways 40 and 41, respectively. lVhen the valve is in the position shown in Fig. 3 the air will pass into the valve and therethrough so as to supply the upper end of pipe 32 vith compressed air, which air will pass downwardly into pipe 3 as heretofore described. lVhen the valve member 37 is in the position shown in Fig. 3 air is being supplied to pipe 32 and pipe 6 is exhausting through the exhaust passageway 38 in the valve and through the passageway 40 to the atmosphere. If the valve should be turned until passageway 42 registers with the pipe 6, pipe 32 would exhaust through the exhaust passageway 41 andfcompressed air would be supplied to pipe 6 for o 'ierating the parts in pipe 4 as heretofore described.

In order to provide means for automati- (ally movingthe valve member 37 back and forth and for alternately supplying compressed air to pipe 6 and pipe 32 and'alternately exhausting said pipes, the buckets or tanks 43 and 44 (Fig. 1) have been provided together with the parts connected thereto. These buckets are pivotally mounted at 45 and46, respectively, to a lever or walking beam 47 pivotally mounted at 48 on the standard or support 49, which standard or support is provided with a base 50 held in position by any desired means. The walking beam 47 is provided with uprights 51 and 52, which uprights have apertured extensions 53 and 54 to which cables or ropes 55 and 56 are secured, said cables or ropesbeing in turn secured at 59 and 60 to the cable or rope 61. The cable or rope 61 is secured substantially midway between the ends to thegrip 62 of the handle or lever 63 rigidly secured to the stem 64 of the valve member 37, while the ends of. this cable or rope are secured to the sliding plates 65 and 66 loosely mounted on bar 67. Bar 67 is connected with the uprights 51 and 52 and consequently rocks therewith. A weight 68 is slidingly" mounted on the bar 67 and is designed to assist the weight of the buckets or tanks 43 and 44 and in turn the valve member 37. The springs 69 and 70 are provided for cushioning the blow of this weight. a

The tanks 43 and 44 are intended to accommodate water or other liquid which is usually suliicient to almost fill only. one

tank. When the air is turned on to the pipe 32, as shown in Fig. 3, air will not only pass down pipe 32 into pipe 3 but will also pass into aby-pass or pipe 1, which by- I will at the same timebe forced into tank J l-3 and consequently will force the water therefrom through the pipe 7 6, and flexible tube 77 to the valve 78, From valve 78 the water passes through the flexible tube 79 into pipe 80 and from' thence is discharged into tank 1%. The amount of water and the air supplied are proportioned to cause the passageway ofpractically all of the water from tank to tank lat while pipe 3 is discharging, so that at substantially at the completion of the discharging of pipe 3' tank 44: will overbalance tank 73 and weight 68. As soon as the bar 67 has passed the horizontal line in its swinging movement the weight 68 will immediately slide over to the opposite side and strike against plate 66 so as to give an additional quick movement to the walking beam 4 -7 and associated parts and thereby give a quick finishing turn or movement to the valvemember 37 so, as, to fully turn the same to, its new position. In its new position the air will pass into pipefi and also I the auxiliary by-pass or pipe81, while the "air from pipe 32 and the auxiliary pipe or bypass 71 will exhaust as heretofore described. through pipe 6 for operating as heretofore described, air will also pass through the by-pass S1 to the valve 82 and from thence through the flexible hose 83 to the inlet pipe 8% which is formed similar to pipe 74 and is provided with the same form of discharge head. This feeding of air into the tank 'or bucket-'44: will of course cause the water to be returned to the bucket or tankj43 by thepath heretofore described, and when the return ofthe water has been completed or substantially completed the weight 68 will again move longitudinally of the bar 67 stopping.

As the .air passes downwardly .As shown inFig; 1,. a screw 91 isfprovlded which rests against the stein (i l of valve 37 for holdmg the valve against its seat, said screw being carried by a bracket 92 and tormmg part of the-casing The buckets ortanks -13 "and himay be supplied with water,.oil or any otherliquid as may and Si and may be drawn at any time through valves 95 and 96. 'The passage? ways a0 and 4:1 preferably merge into an exhaust elbow 97 shown particularly in Fig.

1, which elbow may extend toany suitable discharge point as may be desired.

What I claim is 1. In a pump, a plurality of partially submerged tubular members, air operated means in'each of said tubular members for controlling the flow ofwater therefrom, an oscillating valve; for controlling the air admitted to said tubular members, a pair of .feed pipes for driving air from said valve into said tubular members for alternately supplying and exhausting the air, and

means for moving said valve so that compressed air will be alternately supplied to said air pipes and alternately exhausted,

therefrom, said meanscomprising a pivotally mounted beam, a member for connecting sponding position and when the beam. is

moved to the other position the valve will be turned to its opposite position, pair of buckets pivotally connected to said beam, tubular members connecting said buckets so that the contents of one bucket may pass into the opposite bucket, a by-pass connected to said buckets and to the first mentioned air pipes whereby when .the first mentioned air pipes are being exhausted a corresponding bucket will be exhausted and when the air pipe contains air under pressure some of the air will move into one of the buckets for forcing the liquid therein into the other bucket for over-balancing the lever and thereby turning the valve.

a discharge outlet member arranged above said valve, a division member arranged above each of said discharge outlet members, 7 each of sald dlvlslon members having a passageway therethrough, a plurality of uprights connected with said division members and acting as a guide,- afloat arranged within said guide,said float being formed with a packing on the lower end adapted to rest against said division memberfand bedesired through suitable inletmembers I said means, a mechanism for swinging said valve from one position to another, said mechanism comprising a walking beam, means for connecting the walking beam with the valve so that the valve will be turned upon each movement of the walking beam, a bucket pivotally connected to each end of said walking beam, a liquid weight ar-- ranged in one of said buckets, a pipe connecting said buckets together so that said liquid may be forced from one bucket to the other so as to overbalance said walking beam. and thereby shift said valve, and means connecting the outlet ports of said valve with said buckets so that the lower bucket may receive air under pressure-for forcing the liquid into the other bucket, and a sliding weight associated with the walking beam for assisting said buckets by ivin a uick turnin movement to the b #1 walking beam after the same has reached a substantially horizontal position.

4-. Ina pump of the character'described, a pumping mechanism adapted to be partially submerged in water, a valve for directing air to said pumping mechanism for operating the same, a pair'of pipes for leading the air from the valve to the pumping mechanism, said valve when in one position supplying compressed air to one of the pipes and exhausting the other, when in the opposite position, the operation being reversed, and means for moving said valve from one position to the other, said means comprising a walking beam, flexible means connecting said walking beam with the valve so that when the walking beam is moved from one extreme position to the other the valve will be correspondingly moved, a closed bucket or container pivotally mounted at each end ofsaid walking beam, one of said buckets being adapted to contain a predetermined quantity of liquid, means defining a by-pass for each of the buckets extending from the air supply pipes to the pumping mechanism to the re spective buckets so that the bucket containing the liquid will be supplied with air under pressure simultaneously with part of the pumping mechanism and thereby cause the empty bucket to become filled and over balance the walking beam which automatically reverses the valve and thereby the air supply to all parts of the device so that the action is repeated.

5. In a pump of the character described, a pumping mechanism arranged to be partially submerged, a pair of air pipes leading to said mechanism, a valve for alternately supplying and exhausting said air pipes whereby the pumping mechanism will operate alternately, and means for moving said valve from one position to the other for causing an alternate supply of air to be turned on to saidrpipes, said means comprising a pivctally mounted walking beam, a member connecting the ends of said walking beam with the valve so that when the walking beam is moved from one extreme position to the other the valve will be likewise moved, a container pivotally mounted at each end of said walking beam, one of said containers being adapted to contain a pre determined quantity of liquid, means defining a bypass from said air pipes to said containers, there being an independent bypass for each container, the respective bypasses communicatingwith different airpipes whereby the containers are supplied with air and exhausted simultaneously with the air pipes, and means providing a communication between the containers for directing the water from one container to the other when air is forced into the container carrying the liquid, thus causing the containers to alternately overbalance the walking beam and thereby automatically shift at predetermined intervals the valve from one position to the other.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
